END WALL FOR RAILWAY CARS.

Application led October 12, 1926. Serial No. 141,200.

My invention relates to the construction of a railway car having an end wall made of one or more metallic plates or panels secured together and formed with integral reinforcing and stitliening means to resist the thrust of shifting loads. While efforts are made to block the lading inthe car, the shocks caused by the heavy locomotives, the emergency air brake and the classification hump tear the lading away from its moorings and throw it against the end of the car. The invention is readily adaptable to box, gondola and other types of railway cars.

One of the objects of the invention is to provide a wall element which has great strength to resist the torsional and weavingl stresses which exist in a railway car when moving in service. These stresses are caused by the inertia of the roof and superstructure when the train is suddenly stopped; rough or uneven track; the superelevation of the track on curves; the lateral inertia in rounding curves; eccentric thrust due to the lading being secured to one side of the car; the cars being cornered; the use of push pole pockets, etc. Such stresses rack and distort the superstructure which decreases the life oi the car, and also causes the car to leak grain, sand, and other such material. Furthermore, such stresses cause leaky roofs and leaky and inoperative side and end doors.

An object of the invention is to form the meeting edges of the metallic plates of an end wall so as to provide an integral stiiener or beam.

In the drawings:

Fig. 1 shows an end of a railway box car with my device applied thereon. j

Fig. 2 is a section on line 2-2 of Fig. l.

Fig. 3 is a section on line 3-3 of Fig. 1.

Fig. 4 shows a modified form.

In the drawings the usual parts of the car are shown, such as end sill l; end plate 2 and corner post 3.

In the preferred form the end Wall comprises a central metallic plate 4 which is bent adjacent each vertical edge to form a web 5, which web is bent to form a flange 6. On each side of the central plate is a metallic plate 7 having a similar web 8 and flange 9 at their respective margins adjacent ther central plate. Each of the flanges of the central platekis secured to one Vof the side plates and the flanges of the side plates are each secured to the central plate and spaces 10 are provided between the adjacent Webs of the side and central plates, respectively.

This overlapping construction forms a very strong box girder which is capable of acting as a post to sust-ain the roof loads of the car and also forms a very strong beam to resist the horizontal loads imposed upon the end wall and transmit them to the end sill and end plate, respectively7 and furthermore, acts as a stiffener toprevent the end wall from buckling due to the lateral embossment and the Webs and Hanges of the central plate 12 are terminated within the embossments of the side plate.

Various combinations of embossed and plain plates may be used and also any number of plates may be used and the box girders may be of different depths in the same end Wall if desired and all ot these modiications would come within the scope of the invention, but for convenience, I have shown and described an end wall comprising only three plates.

The Width of the space 10 between adjacent websof the adjacent plates may be varied if desired (as shown in Fig. 4) as the strength of the box girderconstruction to resist horizontal loads from the inside of the car will vary according to the width of this space. Y

The Wooden lining 13 is nailed to the nailing strip 14 which are secured (preterably bolted) to the end wall adjacent the box girder.

I claim:

1. An end wall for a railway car comprising two metallic plates, each formed with a body, a web, and :L flange, the flange of each plate secured to the body of the other plate with zt Splice between said webs.

2. An end wftll for L railway enr comprising two inelnllic plates, each formed with n body, a web, `and nitlange, the flange of euch-plete Secured ,to the body ofthe other plate with n. Space between Suid webs Sub- Stantizilly equal in widtlilo the depth of said webs.
